Riff

Riff is a free Chrome extension that helps you reply on X, LinkedIn, Facebook and Instagram. You paste your rough point. Gemini Nano, the AI built into Chrome, writes a fresh reply for that exact post. You read it, edit it, and press send yourself. It also answers DMs, drafts your own posts and X threads, and learns your voice. Everything runs on your computer: no account, no API key, no servers. Writes in English, Spanish, German and French.
